I saw a Dateline or some show like it, that talked about how the government is selling off of many of their older missile silos and lands. They were very cheap, and were even cheaper depending on location. I think the hippie that bought the missile silo featured in the story bought it and the surrounding land for a total of $50,000. Not bad for an installation that cost several million to build. It was out in the boonies, but being a former nuke silo, it had all the self sufficiency stuff you would need to make it livable; generators, plumbing, etc. The layout was killer, the structure was fully intact sans the missile. It still had the giant launch tube, 2' thick blast doors and all the cool passages and tunnels you could want for closet space. It was like a giant treehouse for adults. If you ever wanted a house that could be easily defended to the bitter end, this would be it.
My only worry would be if the silo was still on some obscure cold war commie map. You would be at ground zero in a SHTF scenario. But if it really came down to that, who would want to survive in a radioactive world anyway.
